Review on Fragmentation in Distributed Database Environment

Fragmentation Techniques for Ideal Performance in Distributed Database – A Survey

“…There have been 3 main fragmentation forms that are vertical, horizontal and hybrid / mixed fragmentation. Vertical fragments are attribute subsets while horizontal fragments are tuple subsets (Kaundal et. al, 2014).…”

“…There has been a recent trend away from centralized database systems for a number of reasons, researcher moves to distributed database due to some drawbacks of centralize database such as expensive communication costs, inaccessibility in situation of system breakdown and a lone source obstacle (Kaundal et. al, 2014 andVerma, 2016).…”

“…Nonetheless, the key enthusiasm underneath the idea of distributed databases is the well-organized administration of massive quantity of data with bigger accessibility and decreased communication cost (Kaundal et. al, 2014 andVerma, 2016).…”

“…The distributed processing of databases is the appropriate way of boosting data efficiency. But perhaps the effectiveness of query processing is a crucial problem in the database system, because applications for decision support need limited response times (Kaundal et. al, 2014).…”

Generalization of the Distributed Database with Specialization and Correctarisation on specific Query

“…The work proposed in this paper tends to analyse the time required to extract the Generalise [3,4,6,7,8] the datasets achieved from different databases, scattered over different sites, whether Heterogeneous or Homogeneous databases. The analysis is done by comparing with extraction of ungeneralised datasets and Generalised datasets.…”
